I have 82 J and have read many of Deakin's and Busch's articles on running WOT all the time. At low altitude cruise I am becoming more comfortable with it but the descents at low RPM I'm not. I was cruising level last night coming home from the office at 8500 feet, 2500 RPM and 8.7 GPH LOP. When it came time for my descent I simple pointed the nose down and established a 700 FPM descent and as the airspeed would climb I would reduce the RPM. Reducing the RPM is effective at slowing the plane down enough to prevent it from going into the yellow arch but by the time I pass through 4500 feet and I'm at 2100 RPM it just doesnt feel smooth in the plane. If I richen it up it doesn't help and it just seems to get worse as the MP gets higher and the RPM stay low. So at this point I reduce the MP and increase the RPM to get where it feels good to me again but leave the mixture alone. I am questioning if the technique is good in the 4 cyclinders vs 6 cyclinders because the 6's will run smoother. For those that fly WOT on their descent can you share your experience with us? Karson
